Weird one. MCDP test 66 (sensor position) showed the Left A/P Rudder Servo at 20+ degrees with hydro on. Hydro off..... it fell back to 0.

Swapped left and center FCC's. Normal left, normal right??? Swapped back, messed up again.
  
  
 
  
  
Shot the servo coils..... 140'ish for left. 130's for center. (The circled "A" on the print represents 26VAC sensor excitation).
  
  
 
  
  
Replaced FCC..... All good!!

    Sure as shit.... after looking at image of print above, I shot the elevator servo.

    This story has more to go as to "if" the FCC actually fixed the problem.
